The beloved baggy cloth cat Bagpuss is fifty years old in 2024. We celebrate his birthday by visiting Sandra Kerr at her home in the Northumberland village of Warkworth. Sandra co-wrote and arranged the music for the series and provided some of the voices. In her cosy music room she shows us her Bagpuss souvenirs, reflects on the show’s enduring appeal and sings one of the songs. Then, on a walk along the River Coquet, Sandra looks back to the folk revival of the 1960s, recalling working as a nanny for Ewan MacColl and Peggy Seeger in exchange for music lessons. Finally, she’s joined by her daughter Nancy Kerr to play traditional Northumbrian dance tunes. A warm, fascinating and entertaining meeting with one of the enduring stars of the folk world.
